This account is currently locked out because a brute force attempt was detected. Please wait a few minutes and try again. Attempting to login again will only increase this delay. If you frequently experience this problem, we recommend having your username changed to something less generic.

My question is how can I customize the message that is displayed to the customer when his account is locked out due to too many incorrect attempts. With the locales I can change the message as described in the above mentioned post but it shows after the first incorrect attempt.
